Ok, so the sun appears to move westward on a daily basis. But eastward through the stars on a yearly basis. I am supposed to explain both the daily and yearly motion of the sun using a few paragraphs with definitions and diagrams. For the year I basically have to explain and draw the sun's eliptic through the zodiac. Using a diagram like this. http://www.dur.ac.uk/john.lucey/users/solar_year.gif My question is, what direction is the sun moving in this diagram? It appears to be moving westward but cant I tell by the RA that it is really moving east? What it is really doing is lagging behind the stars right? Which makes it seem to drift eastward through them. And this is caused by precession?
